Application filed october 5, 1903. Serial No. l155,191.

To all 'wlw/u it 'may concern lie il known thaL hll'AunnY lllllnioineii, a citizen of the llnited States, residing' at lhillipsburg, in the county of Narren und Matr-of New Jersey, have invented Certain new and useful linproi'en'ients in Spring llrheels; and l do declare the following to lie a full, elear, and exactl description of the in Vention` such as will enable (nhers skilled in the art lo which it appertains to uialie and use the suine.

This invention relates to improvements in spring wheels. v The object of the iiivont'ion is lo provide nv wheel of this Character which will be strong and dur-,ble in construction, possess- .ing all the resiliencyv and advantages ot :i

pneumatic-tired wheel, and e'liniinutiiig the disadvantages and objeelions of the hitter by the use of a solid forni ot' tire.

lVith these and other objects in riew, the invention consists ot certain novel. features of eonstruotion, eolnbination und :i1-range nient of parte as will be deserihed and partieularly pointed out inthe appended elainis.

ln the ziceonipanu'ing dra wing, llie'nre l u sido View of a wheel eonstrueted in aeeordaneo with the ilirenlion; Flo'. Q is u trans- Yerse sectional View of the suine, and llig. Cl is an enlarged vertical seetional View through one of the spokes, its hub-attaching yoke and the spring connect-ions between the suino and the riin,

Referring more pnrlfieularly to the drawin;n l denotes the wheel, which Consists of a rin', 2, on which may be arranged any desired forni of tireVl. ln the inner sido ot the riin is .formed a series of threaded seeliets, 4, said socket.; oeingr preferabl).7 arranged in pairs, as shown ln the sockets, l, are serewed short@ nipples, 5, haring threaded outer ends on which are screwed tubular nylindors, G, in theI inner ends olf whieh are screwed bushings, 7.

Slidably mounted in the bushings, 7, and cylinder. t5, are pluuo'eror pressure rods, S, in which near their outer ends is arranged :L transversely disposed pin, l), the ends of which project beyond the sides of the rod, as shown. Arot'jtnd eaeh ot' the, plunger rods, :L coiled spring'. lll, one-half ol whieh is disposed on each .side olf the pin, ll, the latter serving;` to hold the spriiur in operative posh tion on the rodi Arranged in the orlinders,

i t5, adjacent to their opposite, ends are stop pins, l2, said pinsl beiney arranged through the ovlinders tangentially or toene side of the plunger rods, said pins being adapted to il'orn; stops against whieh the ends of the spring. lll, bearso thai each portion of the spring on the opposite 'sides of the pin, l), serres as a eushion when the plunger rod is pushed inwurtlliY or drawn outwardly from the cylinders, thus yieldingly securing the plunger rods in place.

l`he inner ends or the plungerrods, 8, are provided with ti-'ansrersely disposed prissages to reeeire a pivot pin, 13, by lnenns of which said ends of the rods, are pivotnlly ronneeted togelheifin pairs. v'.lho opposite ends of the cross heads, lili, have formed therein elongated apertures to receive the apertured inner ends of the plunger rods, thus lwrinittingv said rods to be loosely piv oted thereto by means ol the pivot pins, 13, hereinbeir'ore described.

The eross heads, 14, are formed on the outer ends of radinllv-projeeting spokes, 15, the inner ends of whieh are connected to 'the' eenter ot lu1battaching' yoles, 16. The yolres. .16, are arranged transversely of the wheel, and at right-angles to the cross heads, M, and the inner ends of said yokes are secured to radially-projectingflanges, 17, on the hubs` 1S, preferablyv by means of transversely disposed pivot bolts, 19, which are passed through said flanges, and the ends of the yoles, as shown.

rl`he. inner ends of the Cylinders, 6, are spaced apart or held in proper position and braced by inea-ns of on annular bracing hoop or band, 20, said band beinl provided with apertures. 2l, which are arranged in pairs and spared apartI to the proper distance to rt'eeire the bushings, i', in the inner ends of the eylindei's. said ends bearing against the outer side ot the ln'aeiirghoop, as shown.

A wheel (.fonsl'rueted as herein shown and t deseribed will be yieldable. in all direct-ions so that the rehiele sluiported thereby will bo eushioned aeainst jolts or jars caused by the wheels passing orer rough surfaces or obstruelions.

,luy suitable tiro may be used in Connection with the wheel and the tires nuiy be Seeured to the rim in any suitable manner.

liroin the foregoingdescription, taken in eonneetion with the :n.feonilninying drawing', the eonstruetion and operation ot the invention will be readily understood without. requiring a more extended explanation. l,

Various eluing'es in the torni, proportion lll) and the minor details of construction may beresorted to Without departing from the principle or sacrificing any of'the advantages of the invention as defined in the ap! pended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is: I

l. In a Wheel of the class described the combination of a hub, a series of spokes, cross heads mounted on the free -ends of said spokes and arranged transversely tothe hub, yokes on the inner ends of said spokes, means for connecting said yokes with the hub, a plu 'ality ot' cylinders secured to the inner face ot' the rim, plunger rods slidably mounted in said cylinders, and cushioning springs arranged o n said rods within said cylinders and means for connecting the inner ends of said rods to the opposite ends -ot' said cross heads.

2. In a wheel of the character described, a hub, a series of spokes having on their outer ends segmental cross heads arranged transversely to the hub, and on their inner ends yokes arranged in line with the hub `and at right-angles to said cross heads, means to pivotally connect said yokes with the hub, a series of tubular cylinders secured to the inner side of the wheel rim, .plunger rods slidably mounted in said cylinr'lers, cushioning springs arranged on said rods andiield and engaged with said nipples, bushings arranged in the inner ends oi' said cylinders, plunger rods slidably mounted in said bushings, cushioning springs arral'lged on said plunger rods to operate in said cylinders, an annular bracing hoop engaged with' said bushings to hold said cylinders in positioma seriesv of spokes having on their outer ends 'cross heads, means to loosely connect the opposite ends ot' said cross heads to the inner ends ot said pairs otplunger rods, yokes formed on the inner ends of said spokes at. right-angles toSai'd cross heads, a hub, and means to pivo tally connect said yokes to said hub.

In testimony' whereof l lhave hereunto set my hand in presence of two subscribing Witnesses. l v
